mg电子游戏娱乐场

系统工程理论研究,特别是从工程开发经验中获得的最佳实践,是指导高科技复杂产品成功开发的保证。系统工程以跨学科的方式解决了整体优化问题,并广泛应用于航空航天等领域的科研,生产和管理的各个方面。

目前,大多数系统工程国际工作都是一般方法研究,侧重于理论描述和学术讨论,有的甚至偏离了主流系统工程的原理和过程方法。尽管一些系统工程出版物涉及在航空航天项目中引入系统工程,但它们不够系统且不够全面。在特定工程项目中使用系统工程的项目管理和工程实践之间仍然存在很大差距。《飞行器系统工程理论与最佳实践》本书概述了李晓光教授30年来在中国和美国的边境航空项目和系统工程与集成方面的经验。

写为功能

从飞机研制成功的角度出发,介绍和分析了系统工程背景知识,系统工程标准,手册和指南,以及国内外顶级航空制造企业系统工程和集成的最佳实践。成功项目的最佳案例的全面性,指导,非常权威和参考价值,对飞机,特别是工业级无人机和商用飞机的发展有很大帮助。本书内容简洁流畅,内容全面,完整,体现了作者的系统工程思想及其多年的研究和实践。

目录简介

在这本书中,李晓光负责编写纲要和草稿,方峰,黄波和徐旭东共同参与了编写工作。这本书共分为两部分。 “系统工程基础”的第一部分阐述并介绍了几种国际主流系统工程理论,标准,方法和工具及其关系,并提供了一个全面的系统工程系统。 “飞机系统工程最佳实践”的第二部分总结了波音,空中客车和中国航空工业公司应用系统工程的最佳实践。开展了航空系统工程的典型应用和实践。总结并期待系统工程的未来发展。

During the development of the B777, systems engineering was understood as “defining aircraft-level top-level requirements, integrating system architecture, allocating requirements, identifying requirements, defining system elements, manufacturing system elements, verifying and validating system-level design, and delivering the entire process of the aircraft” . The “systematic” developed by B777 is based on the requirement of aircraft-level requirements, which traces the requirements down to the various system elements, and verifies and validates them in a timely manner. Developers follow a unified and orderly process and share the same milestones to ensure smooth communication and collaboration. At the same time, system engineering is also a way of thinking and attitude. Once the R&D personnel reach a consensus and work hard, the development process will soon become clear and orderly. The development experience of B777 shows that the system engineering method should be used as early as possible and used by as many relevant personnel as possible.

Boeing believes that systems engineering is a holistic approach to managing complexity from top to bottom and is a multidisciplinary approach to achieving product lifecycles. System Engineering allows us to understand each product as a whole. Improve products from planning, design/development to manufacturing and maintenance. Boeing uses systems to simulate/analyze relationships between system components, requirements, subsystems, constraints, and unit products, and to optimize and weigh important decisions throughout the product lifecycle. Throughout the product lifecycle, system engineers use a variety of modeling techniques and tools to capture, organize, optimize, deliver, and manage system information. Like Airbus, Boeing also uses a downward decomposition approach to aircraft project development as a complex system. Boeing requires a structured relationship between the decomposed requirements and ensures that the decomposed sub-requirements are useful and effective.

xx与空中客车的“大象切片”类似,波音也从多个方面分解飞机项目。如图10.1所示,波音从三个方面打破了客户需求:功能,需求和物理。他们之间也有联系。

△图10.1波音对客户需求的分解

波音公司建立要求的过程如下:

1)确定/收集利益相关者的需求,这一步骤的需求更多地涉及利益相关者的需求(需求);

2)将上述需求转化为产品的顶级要求;

3)基于顶级要求的功能分析和分解;

4)分配分解的要求;

5)定义衍生需求;

6)完善产品的完整要求和设计约束。

从波音公司的需求构建过程中,可以清楚地看到系统工程“NFRP”(需求 - 功能 - 需求 - 物理)过程的背景,从而建立“功能视角”和“需求视角”之间的关系。如图10.2所示,显示了“功能视角”和“需求视角”之间的关系。图中的数字代表上述要求的处理步骤。

△图10.2客户要求分解后“功能视角”与“需求视角”的对应关系

从图10.2可以看出,需求建立的第一步在获得利益相关者的需求后具有完整产品的功能概念,从而在需求建立的第二步产生对产品的顶级需求,从而创造了需求的第三个要求。步骤提供输入,继续分解顶层需求和功能,分解过程集成到需求建立的第四步,匹配分解的需求和功能,并在需求分配过程中反复分析和迭代。它将产生需求建立的第五步的衍生需求。最后,将所有要求清楚地整理出来,然后对应相应的产品功能并确认,完成需求建立的第六步,并在细分后实现相应的功能。产品给出了明确的要求和设计约束。

专家建议

本文从飞机高效成功的发展出发,介绍和分析了国内外知名航空航天制造企业的系统工程背景知识,系统工程标准,手册和指南,以及系统工程和集成最佳实践。结合成功项目的最佳案例,阐述系统工程理论在实际工程中的应用,具有较强的系统性和指导性。它是学习系统工程思维方法的一本很好的参考书。它不适用于飞机,尤其是工业级飞机。由人机和商用飞机开发的工程技术人员非常有帮助。

《飞行器系统工程理论与最佳实践》本书简洁流畅,内容全面,完整,体现了作者的系统工程思想及其多年的研究和实践。本书将由飞机系统工程的初学者,从事复杂航空航天系统工程和实际工程项目的研究人员以及所有希望了解或应用系统工程理论和最佳实践的人员推荐。

"System engineering provides an effective and best practice method for the integration of highly complex system aircraft. It is widely adopted by aerospace research and development and manufacturing companies in various countries, and is regarded by these enterprises as their core competitiveness, especially engineering development experience. The best practices summarized are the important guarantees for the successful implementation of a series of highly complex product development activities, such as military aircraft research and development, civil aircraft airworthiness and evidence collection. National Aeronautics and Space Administration, Boeing Company, European Airbus and other international top aerospace research, Manufacturing units, as well as China Aerospace Science and Technology, AVIC, and COMAC, all use system engineering and system integration methods. For workers engaged in systems engineering research, this book studies system engineering theory to aviation system engineering practice. It is very helpful, especially in the practical part of this book, as an important reference material for practicing system engineering theory in specific projects."

“Although not every aviation industry practitioner has the opportunity to participate in the research and management of system engineering theory and project planning, but as long as the participating projects use the system engineering method, then he must be the system engineering activities. One of the participants. Understanding and mastering the theory and methods of systems engineering will help to understand the various processes in the job and the successful completion of the project. For the aviation industry, which is looking for how to apply the system engineering method in engineering projects. In terms of this, this is a book entitled “Giving people to fish”. It not only combs the systems engineering theory and methods in the industry, but also shows the real-life cases and best practices of the aviation industry system engineering application. It is worth everybody. Aviation industry practitioners refer to and learn."
